Benchy on Ultimaker 5S


Recommended Posts

Posted · Benchy on Ultimaker 5S

Hello all, 


I just finished the annual maintenance of our Ultimaker S5 (lubrification of axis, belt tension adjustment, cleaning feeders, squaring of Y and Y axis, manual bed leveling). Everything was fine except the squaring of X and Y axis were off by quite a lot... I then printed a benchy in the hope of any improvement in print quality (Just to let you know what my 1-1/2 year of experience have been painful). 


I first use PLA from Materio and there was a lot of over extrusion all around. I then think that it might be caused by the  filament grade/inconsistency. I then switch on sylver metallic PLA from Ultimaker. The Benchy came out OK, but the seam is visible, there are some layer inconsistency, there is some ghosting and the overhang are not handle correctly.

I feel the S5 cooling fan are under performing and ghosting is impossible to be fixed.


I used a 0,15mm layer height and use the default basic cura slicing settings. 


How can using only the ultimaker ecosystem (printer, slicer, material) results in less sastifying results (Compare to an Ender3 and Prusa i3mk3s)??? 


Do you have any tips on how to improve prints? Can you share your S5 benchy prints?

    Hi Framar, what version of Cura are you using?


    This is printed as 0.15 basic profile no changes to settings.
    I have tried to mimic you picture angles.




    Photos of 3d prints are a weird thing, somethings will not look as bad on photo and others will look worse then they are! 
    I dont think the print in your picture is that bad, I have seen much worse come from a s5. 


    I have a layer mismatch at the same spot on the hull as you. I think its more a combination of model angle and slicing settings, more then a layer shift. but yes its an inaccuracy.


    The ghosting in my opinion is more likely do to speed, then the cooling fans. The s5 needs to print dead slow to not ghost.


    The drooping in your windows are most likely do to to hige print tempter. it can also be because your fan is not working properly as you mentioned. so be sure that there are no filament stringing trapped in the fan's.


    Here are som more Photos of my print. sorry for the photo quality but im not at the studio today.

    Thanks For thr reply.


    I see more ghosting on your model that mine. So I guess this is what I would have to expect from a S5... I would expect better result from a  $7,750 CAD 3D printer considering that I get better prints from the Prusa i3 Mk3 kit... 

    To get me wrong, I love my S5 but I think price/performance ratio is not competitive...

    Don't forget that S5 prints larger objects than i3 and don't forget that S5 prints Nylon and other high temp materials easily that are difficult or impossible on i3 without modification.  Also S5 is a dual printer that is quite good at printing PVA support which is a difficult feat.


    If you want to print:

    1) Only PLA


    2) Don't mind PLA support (don't need dissolvable support)


    3) only Small parts


    Then the S5 is definitely not for you.  There are other printers that are much cheaper and print with even better quality (for a given speed) like the i3 or the um2go.


    There are other features of the S5 that the i3 does not have that I did not mention but the 3 above are the most important I think.

    Hej Gr5, I would actually like to see how your s5 prints a Benchy.
    Also you Smithy 🙂


    In general I would have liked to see more people join in. 
    it's what 0.35 usd. and 2 hours for a Benchy. 


    The s5 is sold as a Hige end PLA printer, it should be possible to print a Benchy on it. Whether it is a large format printer or not.

    I've seen you like Benchys, so I just printed two 😄

    Since I only do this for hobby-use I sadly can't afford (or justify 😅) an S5.

    • The blue one was the first ever thing I printed on my Ultimaker 2+ with no clue of the printer and what PLA-filament that was, just used the suggested and factory-reset values. That's kind of old already.
    • The grey one is from my old i3 Mega, also printed with PLA from which I don't have a clue what brand or exact temperature-range it is, also just used the default settings suggested by Cura.
    • The white one is also printed on my Ultimaker 2+ but with adjusted acceleration-settings on the printer and an, over the time I use the material, slightly tweaked print-profile. This is not printed in PLA, it's Polycarbonate. 

    All of them are printed with 0.15mm layerheight and were sliced with Cura 4.4.1 (the blue one obviously with an older version, since it's kind of two years old now).

    The only cleanup is the removed brim from the polycarbonate one, the rest is as it came of the printer.

    The white one sadly contains some discolored material that collected up at the nozzle.


    So here are some pictures: (there follows some text below the photos 😄)






















    I cannot really compare the results since those are the only three Benchys I ever printed.


    To be honest, the first thing I thought after printing the very first (blue) Benchy was the same as OP's: "Why the hell can't this ~2000€ machine print a proper Benchy?!". But then I thought a bit further, I bought the Ultimaker not to print cheap-ass PLA, that could also be done with my i3 Mega, I bought it to print more advanced materials that can't be printed at all on that machine. 

    So after learning what the Ultimaker can do, playing around with the settings and using different materials over the time I got some better understanding of what I'm doing and what can be changed to get some aspects better. So after knowing the tools it can also produce a nice (I think it's nice) Benchy. 


    I think you can't expect buying a 6000€ printer will automatically get you perfect prints, it's like buying a expensive Mercedes-AMG, go to a random racetrack and expect the new world-record for that track. You have to know the car, you have to know the track and how they play together, you even might have to consider the weather and stuff. So in my opinion to get good results you need a solid, reliable printer (that has it's price, if that has to be an S5 will stay an open question that everyone has to answer on it's own I think). In my experience it's quite more important to know the materials you use and how they behave in certain conditions. What's also quite important is the design of the printed parts, I think you shouldn't blame the printer, that it can't print something that was intentionally designed not to be printed well (without adjustments) 🤷‍♂️.


    Oh that became quite a long post (my first ever here in the forum 😄) and maybe a bit offtopic, so long story short, in my opinion an expensive printer doesn't make perfect prints on it's own, you have to tell him how to do it properly.


    I also like to print CaliCats over Benchys to test stuff:

    Hm that looks really not that nice for the low speed it is printed 🤔. Are maybe the acceleration-settings a bit high? My 2+ does similar prints (see my blue Benchy) with the factory set quite high settings.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
